CONVEYER.

Application tiled August 7, `19t/Lf Serial No.'730,65l9.,V

My invention relates primarily to a conveyer for moving loads for short distances, such as loads of lumber into and out of the yard, or into and out of a mill; and the 0bject thereof is to provide cheap and efficient mechanism that can be operated with a minimum consumption of power and will produce the maximum of efficiency.

In the dra-wings forming a part of this application Figure 1 is a plan view of my conveyer.

Fig. 2 is an enlarged fragment in side elevation of a portion of the conveyer.

Fig. 8 is an enlarged sectional detail of a part of the conveyer.

Referring to the drawings, my conveyer consists of two or more pairs of parallel rails, each pair comprising rails A and B. These rails may extend the whole distance that the load is to be transported or .they may be made in sections, but each section would be operated in the same manner as if the rails were each a single length.

At suitable distances along and supporting the rails, are pairs of wheels C and D rigidly mounted respectively onthe axles E and F, revolubly mounted in bearings H on sills I, which axles are driven at a suitable rate of speed by any suitable gearing, such as a worm gear J on each sha-ft E meshing with a wormon shaft K and intermeshing gears L on shafts E and F, power being applied to drive shaftK K. l

lVheels C are the driving wheels and are composed of the offset sections C1 and C2 which have a common hub C3. Each section comprises one-half the periphery of the Wheel and is flanged. I

l/Vheels D are the return wheels and are composed of two odset sections D1 and D2, which have a common hub D3. Each section has a iianged circular periphery and is a little less than a half circle and the length of the periphery of each section is the same as that of each section of wheels C plus the vertical distance that the rails A and B travel while being raised or lowered as hereafter explained. l/Vheels D are a little lower than wheels C and the periphery of the sections are a little further from shaft F than t-he periphery of wheels C are from shaft E.

With the rails in the position shown in Fig. 2 the load G is supported by rails A and rails A are supported and moved in the direction of the arrow by fianged section C1, and rails B are supported and moved in the direction of the arrow by flanged section D2. Power being applied to cause the rotation of axles E and F it will be seen that section C1 can cause rail A to travel a distance equal to the length of the periphery of the section engaging rail A and that section C2 is engaging rail B and lifting` it up under load Gr and that rails A and B will then travel together in the direction of the arrow on rail A or forward, and that section C1 will cease to support rail A which will then drop upon section D1 and will be moved in the direction of arrow on rail B or toward the rear. As the points of load support of the peripheries of wheels C and D are directly over shafts E and F, it only requires the minimum amount of power .to revolve the shafts, and the maximum load for the amount of power consumed is moved forward. By reversing the revolution of the shafts, the load can be moved backwards. The movement of the rails toward the rear is so timed that when their rearmost travel is reached, they are rea-dy to be engaged and lifted up and then carried forward by the driving wheels.

By this construction, the load is moved forward in the same plane and no power is lost in raising and lowering the load as shown in U. S. Patent No. 666,865. lVheels C and D may he called mutilated wheels.

Having described my invention, I claim:

l. A conveyer comprising'a plurality of parallel rails, means to support and move said rails comprising driving wheels and return wheels, said wheels being mutilated wheels, the driving wheels being adapted to alternately move the rails to a supporting and load carrying position and to move them either forward or backward as desired, the return wheels being adapted to alternately move said rails backward or forward as desired; and means to cause the rotation of said wheels.

2. A conveyer comprising a plurality of pairs of parallel rails; axles extending trans versely to said rails and beneath the same; a portion E of said axles having rigidly mounted thereon driving wheels, each wheel comprising a hub having mounted on the sides thereof offset sections, one offset section being adapted to support and move one of a pair of rails for one-half the revolution of the wheel, and the other oiset section other rail of the pair to the rear; and means loeing` adapted to Support and move the other to revolve said axles. 0f a pair of rails for the other half of the 3. n a deviee of the character described revolution of the Wheel, the other portion F load moving' Wheels having' the peripheii/7 5 of said axles having` rigidly mounted therethereof composed of oifsetsections, each Sec 15 on return Wheels, each Wheel comprising' a tion being' the one half of a Circle. hub having mounted on the sides thereof Oif- In Witness that I elaiin the 'foregoing' set Sections, the section on one side being have hereunto subscribed my naine this lst adapted to return one of a pair of rails to day of August, 1924.

10 the rear and the other section to return the JAMES GEDDES.
